Somehow I developed a crack in my windshield. I reported it today, and made an appointment to have it fixed tomorrow morning. But between the time I left home this morning and the time I got home this afternoon, the crack had grown. I'm not very optimistic that it's going to be able to be fixed, and I'm wondering instead of my windshield will have to be replaced entirely.
I have no idea what caused the crack. I don't recall anything hitting my windshield hard enough to do it. I suspect the crack has been there for a while, and the rain turning to snow we got earlier this week caused it to grow.
